in the dev_test branch the code already has commited, but i still get this error, maybe other problem? or i mush to install other version with blend? `

def __update_shader_input(self, name, val):
    mat = self.material
    if mat.name.startswith('mmd_'): # skip mmd_edge.*
        return
    self.__update_shader_nodes()
    shader = mat.node_tree.nodes.get('mmd_shader', None)
    if shader and name in shader.inputs:
        if hasattr(shader, 'node_tree'):
            input_socket = shader.node_tree.inputs[name]
            if hasattr(input_socket, 'min_value'):
                val = min(max(val, input_socket.min_value), input_socket.max_value)
        shader.inputs[name].default_value = val`

thanks to replay

i only modify the material.py in the location of blender addons, and reopen blender, but nothing happened. still get suck, i'm so sorry to bother you

currently, mmd_tools is developed in another repository linked above. only blender-v4 branch is compatible for Blender 4.0.
